[0002] Plastic hot stamping molding equipment is widely used in the production of precision components such as automotive interior parts and appliance housings. The clamping device of the guide pillar (guide post) is a core mold-locking mechanism, and its performance directly affects the mold positioning accuracy and product yield. Currently, hot stamping molding equipment typically uses a hydraulic system to clamp the guide pillar, directly pushing the single-sided clamping block to close via a hydraulic cylinder piston rod. This method relies on parallel double cylinders or precision-machined mechanical limit blocks to ensure synchronization. However, insufficient synchronization accuracy makes it difficult to control the clamping force and position, resulting in low clamping precision. Furthermore, assembly tolerances can lead to uneven loading and jamming, causing unilateral force deviation in the guide pillar, accelerating mold wear, and hindering the development of high-speed and precision hot stamping equipment.
